STMicroelectronics HCF40107M013TR

Overview

HCF40107M013TR from STMicroelectronics is a dual 2-input NAND buffer/driver IC with open-drain n-channel outputs, designed for high-current sinking interface applications. It delivers 136 mA typical sink current at VDD = 10 V and VDS = 1 V, supports 3–20 V supply operation, and features ≤100 nA input leakage at VDD = 18 V - used in triac-driven lamp and solenoid control circuits.

For engineers reviewing the HCF40107M013TR datasheet, HCF40107M013TR pinout, HCF40107M013TR application, or HCF40107M013TR equivalent, key selection criteria include open-drain output compatibility, wired-OR capability, sink-current rating across 5/10/15 V rails, and -55°C to +125°C industrial temperature range compliance.

Technical Context

The HCF40107M013TR implements two independent CMOS NAND gates with unbuffered open-drain n-channel output transistors - no internal pull-up, requiring external RL to VDD. Each output supports up to 136 mA sink current (typ.) at VDD = 10 V and exhibits ≤100 nA input leakage at 18 V.

It complies fully with JEDEC JESD13B B-series CMOS specifications, operates from 3 V to 20 V, and guarantees noise margins of ≥2 V at VDD = 10 V. Propagation delays are 45 ns (tPHL, typ.) and 60 ns (tPLH, typ.) under 10 V/120 Ω load conditions.

FAQ

Is an external pull-up resistor required for HCF40107M013TR outputs?

Yes - the outputs are open-drain n-channel MOSFETs with no internal pull-up. An external resistor (typically 1–10 kΩ) must connect each output to VDD or another logic-high rail to establish defined high-state voltage. Failure to install pull-ups results in floating outputs and undefined logic behavior.

Can HCF40107M013TR drive a 12 V relay coil directly?

Yes - with VDD = 12 V and a properly sized pull-up, the device delivers ≥100 mA sink current (min.) per output, sufficient for most 12 V/400 mW relay coils (e.g., 30 Ω coil impedance). Ensure PCB layout minimizes trace inductance and includes flyback diode protection across the coil.

What is the maximum capacitive load the outputs can drive reliably?

The datasheet specifies dynamic testing at CL = 50 pF. While higher capacitance (e.g., 100–200 pF) is tolerable, rise/fall times degrade linearly - at 200 pF and VDD = 10 V, tPLH increases to ~180 ns. For >100 pF loads, verify timing margins in final system with actual probe/jig capacitance included.

Does HCF40107M013TR support 3.3 V logic inputs?

Yes - VIH is 1.5 V min. at VDD = 5 V and scales proportionally; at VDD = 3.3 V, VIH ≈ 1.0 V (per JEDEC B-series ratio), well below standard 3.3 V CMOS logic high (≥2.4 V). Input thresholds remain compatible without level shifters when driven by 3.3 V microcontrollers.
